Rubber Feet Support for Prusa MK3

thingiverse

Another option for you if your feet are popping off. This should keep them in place. Let me know if they still pop out, and I will add some additional support. I can push mine around on the table with a 10kg weight on top and they stay put. You'll need: 4 m3 t-nuts that fits in the aluminum extrusion. There are some on Thingiverse that you can print. I had some steel ones laying around. Get the ones you can put in without removing anything. They go in sideways and twist. 4 10-12mm m3 screws. 8mm can be used, but they are a little hard to fit with washers. It's the same screws that come with the printer. 4 m3 washers (optional) They put more even pressure on the hole. You place the feet in as you normally would, then put the t-nut in and slide my model over and screw it down. You might need to wiggle the rubber around a little to make it flush with the aluminum profile. There is a version included which use screws on both sides. I have not tested this model, but I don't think it's necessary to use it. Also let me know if the holes get messed up. Mine got a little messy using PETG. PLA might be better.
